It is often useful to find other contracts referenced by a particular contract. Let's assume you want to search for contracts that fulfill conditions similar to the [Parity Multisig Wallet Bug](http://hackingdistributed.com/2017/07/22/deep-dive-parity-bug/). First, you want to find a list of contracts that use the `DELEGATECALL` opcode: It is often useful to find other contracts referenced by a particular contract.
